Where do you get your Java? Today's Java is vastly different, although it is still true to its root principles of robustness, portability, and ease of programming. Your options for where to get your Java have similarly evolved. If you download Java directly, you might think that you can only get an official version from Oracle. This is no longer the case. In fact, there are a number of vendors that now provide their own Java distributions that are 100% compatible with the official Java specification. So, you might be wondering: Are they all the same? If not, what differentiates them? How do I know which one to use? To learn more about the ever-changing Java ecosystem, read on. This article will cover: The history of Java, covering the evolution of Java from Sun to Oracle, and the adoption of OpenJDK.

Java's "write once, run anywhere" (WORA) capability allows developers to write code that can run on any device that supports Java. Key Features of Java Object-Oriented: Java follows the object-oriented programming paradigm, which means it uses objects and classes to structure software programs. This approach helps in organizing complex code and enhances reusability and scalability. Platform Independence: Java code is compiled into bytecode, which can be executed on any platform with a JVM. This makes Java highly portable and ideal for cross-platform applications. Robust and Secure: Java provides strong memory management, automatic garbage collection, and exception handling, making it robust. Its security features, such as bytecode verification and the absence of pointers, help prevent memory corruption and unauthorized access. Multithreaded: Java supports multithreading, which allows concurrent execution of two or more threads. This is essential for developing high-performance applications that require multitasking. High Performance: While Java is an interpreted language, its Just-In-Time (JIT) compiler improves performance by compiling bytecode into native machine code at runtime. Distributed: Java is designed for distributed computing, making it suitable for building applications that run on networks, such as web services and enterprise-level applications. . Conclusion Java's enduring popularity stems from its powerful features, cross-platform capabilities, and extensive community support.

some interesting facts about Java: 1)Original Name: Java was initially called “Oak” after an oak tree that stood outside the office of James Gosling, one of its creators. The name was later changed to Java, inspired by Java coffee. 2)Accidental Invention: Java was created by accident. James Gosling and his team were trying to clean up C++ while working on a set-top box project at Sun Microsystems, which led to the creation of Java. 3)Popularity: Java is one of the most popular programming languages in the world. It is used by 95% of enterprises as their primary language. 4)No Pointers: Unlike C++, Java does not use pointers. This design choice was made to enhance security and robustness. 5)Final Keyword: In Java, the final keyword has multiple meanings. It can be used to define constants, prevent method overriding, and inheritance. 6)Platform Independence: One of Java’s key features is its platform independence. Java programs can run on any device that has the Java Virtual Machine (JVM), making it highly portable. 7)Widespread Use: Java is extensively used in Android development. The Android operating system relies heavily on Java APIs. 8)High Demand: Java developers are in high demand. The median salary for a Java developer is around $83,975.

𝗗𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲 𝗯𝗲𝘁𝘄𝗲𝗲𝗻 𝗝𝗗𝗞, 𝗝𝗥𝗘, 𝗮𝗻𝗱 𝗝𝗩𝗠 𝗝𝗗𝗞, 𝗝𝗥𝗘, and 𝗝𝗩𝗠 are core concepts of Java programming language. We don’t use these concepts in programming. But, as a Java developer, we should know about them. 𝟭. 𝗝𝗗𝗞 Java Development Kit aka JDK is the core component of Java Environment and provides all the tools, executables, and binaries required to compile, debug, and execute a Java Program. JDK is a platform-specific software and that’s why we have separate installers for Windows, Mac, and Unix systems. We can say that JDK is the superset of JRE since it contains JRE with Java compiler, debugger, and core classes. 𝟮. 𝗝𝗩𝗠 JVM is the heart of Java programming language. When we execute a Java program, JVM is responsible for converting the byte code to the machine-specific code. JVM is also platform-dependent and provides core java functions such as memory management, garbage collection, security, etc. JVM is customizable and we can use java options to customize it. For example, allocating minimum and maximum memory to JVM. JVM is called virtual because it provides an interface that does not depend on the underlying operating system and machine hardware. This independence from hardware and the operating system makes java program write-once-run-anywhere. 𝟯. 𝗝𝗥𝗘 JRE is the implementation of JVM. It provides a platform to execute java programs. JRE consists of JVM, Java binaries, and other classes to execute any program successfully. JRE doesn’t contain any development tools such as Java compiler, debugger, JShell, etc. If you just want to execute a java program, you can install only JRE. You don’t need JDK because there is no development or compilation of java source code is required. Now that we have a basic understanding of JDK, JVM, and JRE, let’s look into the difference between them. 𝗝𝗗𝗞 𝘃𝘀 𝗝𝗥𝗘 𝘃𝘀 𝗝𝗩𝗠 Let’s look at some of the important differences between JDK, JRE, and JVM. • JDK is for development purpose whereas JRE is for running the java programs. • JDK and JRE both contains JVM so that we can run our java program. • JVM is the heart of java programming language and provides platform independence.
